AUGUSTE nlnrraivitbr New Yoan, u. Y.

...citizen of Germany, residing at 305 `West Fifty-fifth street, New York city, county and State of New York, `have invented certain new and useful Improvements in Tire- Protectors, of which the Afollowing is a specification. i

This invention relatesto a tire protector of novel construction which incases the tire tube in a dustand water prooi:I manner, permits the tube to be laterally deflected under load pressure without encountering ,.frictional contact with the protector, is rigidly secured to the wheel rim, and effecy tively armors the tube against punctures.

In the accompanying drawing: Figure 1 is aperspective view of part of a tire protector embodying my invention; Fig. 2 a

` detail of the abutting strip-ends and adj oining parts; Fig. 3 a section on line 3, 3, Fig. 2; Fig. 4 a section on line 4, 4, Fig. 2; Fig. 5 a perspective view of one of the central armor bars; Fig. 6 a similar view of one of the lateral armor bars; Fig. 7 a detail of a gored portion of the flexible strip, and F ig. 8 a section on line 8, 8, Fig. 7.

The outer tire tube 10 inelosing the air tube 11, is flanged as at 12 for engagement with the wheel rim 13. Over the outer half or tread of tire 10, there extends a flexible covering 14, made preferably of a continuous strip of leather, the edges of which abut as at 15, Fig. 2, said edges being joined to each other, in manner described farther below. To the innerface of strip 14, there are secured at suitable points a number of rubber protuberances 16 shown to be made in the shape of conical plugs, though this shape may be varied without departing from the spirit of my invention. Plugs 16 contact with the face of tube 10, and thus produce intermediate said'tube and strip 14, an air space 17, that prevents a direct Jfrictional engagement between tube and strip, rubber fillets 14a being interposed between the tube and the ends of the strip. The two longitudinal edges of strip 14, are gered at suitable intervals as at 18, and the transverse edges 19 thus formed are drawn together, so as to closely hug fillets 14a.

rlhe inner or wheel portion of tube 10, is encompassed by a sectional steel or other sheet metal casing 2O the halves of which are joined to each other and tothe wheel felly `21 in suitable manner, the drawing Tran-PROTECTOR.

showing themto be provided with flanges 22 whichare perforated forthe reception of bolts 23, said bolts passing likewise through felly 21. Casing 20, is pro-vided on its inner `face with a plurality of sockets 24, into which are fitted rubber plugs or protuberances 25, that engage with their protruding 4ends the bodyof tubelO, so that here also an opposite sides of gore 18, so as to be drawn together by the contraction of the gore. Each pair of opposed buttons 27, 28 is engaged by a common clasp 29, that projects over the junction between casing 20, and strip 14, and has two hooks, one of which encircles button 27 while theother encircles the divided button 28. By lmeans of the clasps 29, the two component parts of the tire protector are thus firmly united and sustained in their relative position, while by taking off the clasps, ,the protector may be readily dismembered.

Strip 14 isl armored by a plurality of metal bars 30, extending transversely over the tread, and by two rows of shorter metal bars 31, itted closely against the ends of bars 30, and located sidewise of the tread,

l the bars 30, being beveled along their edges to permit a free play under load pressure. Bars 30 are rectangular in shape and provided with integral prongs 32, while bars 31 are somewhat pointed andprovided with prongs 33, the prongs 32, 33 being forced through the strip 14 and then upset, to secure the bars to the latter. Underneath the abutting edges 15 of strip 14, there is placed a leather underlay 34 from which `extend outward a plurality of bolts 35, that pass through strip 14 and thence enter sockets 36 formed in those `bars 30, 31, which are locatednear the break of strip 14. Nuts 37 engaging bolts 35 and countersunk in the sockets 36 serve to attach the underlay 34 to the bars, so that in this way the abutting ends of strip 14 are securely attached to each other while upon the unscrewing of the nuts, the strip can be readily removed.

The tire protector constructed as described possesses a number of advantages: The rubber plugs though permitting the play of the tube under load pressure, prevent any acbuttons 27, arranged oppositesectional buttons 28, which are provided on tual contact between tube and protector,N so that objectionable friction is avoided. The e ksteel casing eipects a secure and rigid attachment of the device to the Wheel rim, protects the tube against injury, and checks any lateral deflection of the same, While together,

`with the leather strip it constitutes a dustand watertight inclosure for the tube. Thev metal bars constitute a reliable armor against na1l`s,glass or similarartlcles, and owing; to their trlpartlte construction Will yield readily Aand may be applied Vto tubes freadily accessible `for the purposes of in i spection and repair.

I claim:

, Al. `A `tire rprotector 'comprising a-nietal 1 casing fitted a-gainstthe inner .side of a tire 'e tube, anlieniblestrip fitted againstl the outer side ofwsaid .tube it and having gored longitudinal edges Which are overlapped by the longitudinal edges of the casing, sectional buttons secured to the strip, at opposite sides of the gores, coperating ,buttons secured to the casing, and clasps engaging the buttons of the strip and casing. y l

2. A tire protector comprising ajflexible strip adapted to encompass one portion of a tire tube,anoverlapping,metal casing adapt- `edtoencmnpass yanother portion of said tube, vmeansffor securing the strip to the casing, and resilient plugs projecting fromthe in- Anerlfaces of the strip and ycasing into con! l-tact Withlthe tube. 1" l e *i l AUGUSTE RIEMANN.
